Rockford Fosgate HD24-STG3 Gen 2 Harley Davidson Audio Upgrade Kit (2024+ Street Glide & Road Glide, Plug & Play 4-Speaker System)

Fitment Note:
2023.5+ Harley-Davidson models must have the latest factory software installed before adding the TMA-1000X4i amplifier. The amplifier will also need to be updated and tuned.
If you’re unsure, reach out. We deal with this every day.

Overview 

If you’ve spent any time on a 2024+ Street Glide or Road Glide, you already know the factory system runs out of steam once you’re up to speed.

The Rockford Fosgate HD24-STG3 Gen 2 is built to fix that.

This is a full Stage 3 upgrade with a 1,000-watt amplifier, upgraded fairing speakers, and 6x9 saddlebag speakers. It gives you the kind of volume and clarity you can actually hear at highway speeds, not just sitting in the driveway.

We install a lot of these, and it’s one of the most common setups for riders who want a serious upgrade without getting into a full custom build.

What You’re Getting

This is a complete system designed specifically for 2024+ Harley touring bikes. Everything is built to fit where it should and work with the factory system.

You’re getting:

• Upgraded 6.5" fairing speakers
• 6x9" saddlebag speakers
• 1,000-watt 4-channel amplifier
• Model-specific grilles
• Amp install kit and saddlebag cut-in kit

It’s a true front and rear upgrade, not just a small bump in volume.

How It Performs

The biggest difference with this kit is usable volume.

The stock system falls apart once you’re riding. This setup holds together. You get cleaner highs, stronger vocals, and noticeably better low end.

It’s not just louder. It stays clear when you turn it up, which is what actually matters on a motorcycle.

Installation

This kit is designed as a plug and play system using factory-style connections. No radio flashing is required, and everything is built to integrate with the Skyline OS system.

Typical install time is around five hours.

We install these at all three of our locations, and we also offer on-site motorcycle installation if you want it done at your place or at a rally.

Tuning

The amplifier connects through the RF Connect app, which lets you load preset tunes or make adjustments right from your phone.

Built for Real Use

Everything in this kit is designed for the environment these bikes live in. Water, vibration, heat, it’s all accounted for. This isn’t a garage-only setup.
